Vulnerability Data
In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, a user who does not hold the "admin" or "power" Splunk roles could write dispatch metadata to an arbitrary location on the host by supplying a crafted search identifier to…

a Representational State Transfer (REST) API endpoint and affect system integrity on the host. The vulnerability is possible because Splunk Enterprise does not validate the search identifier before using it to create a dispatch directory. For more information see About configuring role-based user access (https://help.splunk.com/en/splunk-enterprise/administer/manage-users-and-security/10.2/manage-splunk-platform-users-and-roles/about-configuring-role-based-user-access) in the Splunk documentation.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Input validation directly stops untrusted pathnames containing ../ sequences from being used to construct traversals outside the intended directory.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure SDLC practices directly require input validation and path sanitization that prevent directory traversal flaws.
Vulnerability identification processes will discover path traversal weaknesses during code or configuration review.
Least-privilege file permissions and access enforcement can limit the damage from a successful traversal.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Secure coding standards require neutralizing '../' sequences and using safe file APIs, eliminating this exact weakness.
Security testing in development catches path-traversal flaws before release but does not itself implement the control.
Secure development lifecycle mandates input validation and path sanitization that directly prevents directory traversal.
Application security requirements include explicit rules for safe file-path handling and canonicalization.
Secure architecture principles discourage unsafe path construction but do not prescribe the specific coding fix.
Information access restriction can limit which files are reachable, reducing impact but not preventing the traversal vector.
